FR: Add a --remote_upload_mode that mirrors the behavior of --bes_upload_mode

[brentleyjones]

Description of the problem / feature request:

With the introduction of --experimental_remote_cache_async, it's now possible to have to wait at the end of a build for uploads to complete. Similar to uploading for BES, the user might not care that uploads are finished yet before wanting to run another command/build. Just as BES has --bes_upload_mode, the remote cache should have --remote_upload_mode.

Feature requests: what underlying problem are you trying to solve with this feature?

I want the ability for bazel to continue to upload the outputs of local actions in the background, after a bazel command completes. This can speed up certain workflows.

What's the output of bazel info release?

release 5.0

@coeuvre I think this is still a valid FR, right?
